JOHN A. Enrico, or WILLQUGHBY, orrIo COMBINATION Application filed May e,

My invention isa combination ax and adz, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of the 'invention is the provision of a tool having a head adjustable at will to adapt the tool for use as an ax or hatchet or as an adz.

A further object oi the invention is the 19 provision of a tool of the character described having a head including bit or blade and poll portions and means for adjustably connecting the head of the tool with a handle or helve so that the angular relation of the longitudinal axis of the head `of the tool to the axis of the handle can be varied within limits at will and the head can be secured firmly, although releasably, to the handle in any one of a plurality of adjusted positions.

Other objects -and `advantages oit the invention will be apparentrom the following description, and the accompanying drawinOfs, in whichzFigure 1 `is a side elevation of the tool with the head secured to the handle with the axis of 4the head disposed substantially at right angles to the longitudinal axis of the handle and the blade portion of the head in position to adapt the tool for use as an ax or hatchet,

The head oit the improved tool comprises a blade or bit Aportion 1 having the cutting edge 2 .at its outer end. The blade 1 may 5 taper in thickness vfrom its inner to its outer end as shown in Figure l and is integral CII AX AND .ADZL

with a shank which extends from the middle part of the blade at the `inner end of the latter. This shank comprises an enlarged substantially spherical portion 3 and an outer reduced substantially rod-like externally screw threaded attaching end portion l. A terrule comprises an eye portiono `for the reception of an end portion of the ihelve or handle 6. The eye portion 5 is substantially rectangular in cross section, The eye portion 5 of the 'errule is integral with a substantially channel-shaped attaching and supporting portion generally indicated at 7. lThe attaching and supporting portion 7 of the i'errule has a web 'which consists Aof one end wall of the eye portion 5 and a prolongation 8 at the -outer end ofsaid end wall of the eye portion of the errule. The attaching 'and supporting portion 7 of the ferrule also comprises a pair of side anges 9 which may be joined integrally at their inner ends tothe side walls of the zeye ,pon tion 5 of the ferrule, the side walls of the portion 5 and the flanges 9 ol the portion 7 ofthe ferrule being located at opposite sides ot the web of the .attaching and supporting portion 7 of the ferrule. The ianges 9 of the `attaching and supporting portion oi the ferrule are connected vat their outer ends by a vcrossmember 10 which may be integral with lboth the web of 'the `portion 7 of the `ferrule and with the flanges of the portion7 of the errule. The .cross member 10 may have the inner wall thereof slightly convex in curvature from its juncture with the web oi the portion 7 of the ferrule to its outer edge as best seen in Figure2.

A circular opening 11 of Vslightly less diameter than the diameter of the substantially spherical portion 3 of the shank of the head ot the tool is formed in the prolongation 8 or in other words the web of the attaching and supporting portion 7 of the ferrule `at a distance beyond the outer end of the eye portion 5 of .the ferrule which is slightly greater than one-half the width of the blade 1. rlhe outer edges of the lflanges 9 are convexly curved to lie in substantially the arcs or' circles parallel to a circle struck by a radius moving about the center which is coincident with the center ofthe opening 11.

A spacing ring 12 is disposed loosely on the threaded end portion 4 of the shank of the head Yand has opposite lug portions 13 at its inner end extending between the and which constitutes the striking or iin-f pact face of the head of the tool.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The shank of the head is arranged with the substantially spherical portion 3 swiveled in the opening 11 which may be termed the socket for engaging with the spherical or ball portion of the shank of the head. The attaching end portion 4 of the head extends between the flanges 9 of the portion 7 of the ferrule beyond the convexly curved edges of the flanges.

The ring 12 is disposed loosely on the attaching end portion 4 with the lugs 13 between the flanges. The cap 14--15 is engaged with the attaching end portion 4 of the head and can be tightened against the ring so that the head will be secured to the ferrule with the longitudinal -axis of the head disposed at right angles to the longitudinal axis of the handle or helve 6 asshown in full lines in Figures 1, 2 and 4 or with the ylongitudinal axis of the head disposed at an oblique angle to the longitudinal axis of the helve 6, two positions of the head when the longitudinal axis thereof is oblique tothe longitudinal axis of the helve being shown by dash lines in Figure 4. The head of the tool may be secured to the ferrule by means of the poll 14-15 and the presser ring 12 so that the blade 1 will lie in the same plane as the longitudinal axis of the handle 6 as shown in Figures 1 and v2, whereby the tool will be adapted for use as an ax, or the blade 1 may vlie in a plane which extends at right angles to the direction of length of the handle, whereby the tool will be adapted for use as an adz, as shown in Figure 4.

A tool for use in turning the head 14-15 conveniently may have the form of a rod 16 which is adapted to be inserted in any one of a plurality of radial openings` 17 in the body of the cap and then manipulated to turn the cap to loosen or tighten it. `The rod 1G when not in use may be extended between the iianges 9 as shown in Figures 1, 2 and 4 and retained against a groove 18 in the inner wall of the web of the channel shaped portion of the ferrule by means of the loop portion 19 of a substantially U- shaped spring member 20. The latter has the arms thereof bent intermediate their length to provide eyes through which a supporting pin 21 extends. The supporting pin 21 extends transversely of the substan tially,channel-shaped portion of the ferrule and the ends thereof are fast in the flanges 9.

Obviously, the invention is susceptible of embodiment in forms other' than that illustrated in the accompanying drawings, and I therefore consider as my own all such modifications and adaptations thereof as fairly fall within the scope of the appended` claims.
